Pretty sure GSP walks around at around 180-185, so I don't see how everyone is saying he would lose strength and speed at MIDDLEWEIGHT. I can see him definitely having a disadvantage at 205 because of his height and weight, but he could dominate at middleweight just as easily (if not easier) as he does with WW. And the only reason he had to start taking down BJ was cuz he got thumbed in the eye and cut, BJ is notorious for loose thumbs in eyes too; not taking away anything from BJ, he's one of my alltime faves

He took Penn down because he was losing the stand-up.

St. Pierre is not dumb enough to keep standing if he is being out struck. Him grappling with Penn also caused Penn to exert more energy to defend the takedowns, so he won eventually due to his game plan and superior cardio.

I think it's premature for GSP to talk about moving up in weight class just yet. He still needs a rematch with Hughes and possibly Penn (IMHO I feel Penn won the last fight but it was close) and maybe a match with Diego Sanchez before moving up. If he manages to get thru those guys then GSP vs Silva will be a very exciting fight for sure. Some other fighters in the middleweight class that would make some exciting fights for GSP would be Dan Henderson and Denis Kang from Pride but I doubt that would happen. As for GSP in the LHW class, it would be tough for him to succeed with guys like Liddel, Rampage and with Crocop possibly moving down in weight it wouldn't even be close. One LHW fighter I would put my $$$ on GSP to win would be Tito.

OK GSP will never beat Chuck I don't care what anyone says GSP's striking is not as good as people think it is. He doesn't have enough power behind his punches to knock ANYONE out. Hell if I was his size I would love to have a kickboxing match with him. He is not that impressive IMO. I think I could take him in kickboxing (If I was bigger lol).

As for MW, that is a different story. I think Rich would beat him, and maybe even Marquardt and Mike Swick. Silva is 50/50 for me. If GSP can take him down he might be able to pound him out, but if he wants to try and stand and trade with him, he will be leaving on a stretcher. GSP has very good takedowns and very good wrestling on the ground but his standup is kind of subpar. He could be good if he learned how to punch with some more power. I mean the guy is massive he should be KOing people left and right but he has 0 KO's on his record. That tells me he doesn't know the proper way to punch quite yet. But he's only 25 so I'm not saying he will never learn.

We'll have to see what happens at WW before we get all giddy about this though. He should have no problem with Serra, but I personally believe Diego, Penn, and possibly even Hughes stand a fantastic chance at beating him and taking his belt. Not too long and Fitch may be able to take him also.

If he faught Chuck 10 times I think GSP would win once. Chuck is waaaaaaaaaaay above him in many aspects. If Tito and Couture had trouble taking Chuck down, GSP doesn't stand a chance. And there's no way he is on Chuck's level in the striking department.
